Installing
and Updating BfX

Adding an add-in to Excel is easy

For starters, check if your copy of Excel has had all updates.

Excel 2003, 2007 and the 32 bits
Excel 2010 and 2013 use the same version of BfX.xll. BfX.xll automatically
detects which version of Excel is runnung and adapts. The 64-bit
version of Excel 2010 and 2013 use BfX64.xll.(what
is an .xll file?
Should you check it for virusses?)

Using the Installer

Most installations require the automatic installer. On these computers,
auxilary files on which BfX.xll
depends are not present. The installer puts BfX
and some auxilary files
from Microsoft on your computer. However, in the case they are already
there (e.g. they came with another program or a previous installation
of BfX) then you could just swap the BfX.xll or the BfX64.xll for the newer one. That works fast, but you risk that the auxilary files from Microsoft are not updated.

Once installed you can easily check the installation. Just start Excel and enter =bfx_help() in a
cell. When
technically everything is allright one can start immediately (see right
panel on this page) or download the Excel workbooks that
illustrate the use of BfX. If you can't install BfX then start the
trouble
shooting here.

It is not nessecary to know all
the ins and outs of add-in installation, but if you would like to know,
start here.
